An absorption refrigerator is a refrigerator that uses a heat source to provide the energy needed to drive the cooling process. Solar energy, burning a fossil fuel, waste heat from factories, and district heating systems are examples of convenient heat sources that can be used.

In the ammonia-water absorption refrigeration system, ammonia works as the refrigerant and water works as the absorbent. When ammonia leaves the generator in the vaporized state some particles of water vapor are also carried with it, and these are removed in the analyzer and the rectifier.
1 lip 2023 · In this paper, a modified ammonia-water absorption refrigeration system with two pairs of evaporation and absorption processes at different pressure levels is proposed, in order to enhance the temperature matching with the temperature-distributed heat load and promote the absorption heat recovery.
1 kwi 2020 · The absorption refrigeration system is defined as a thermally driven refrigeration technology for exploiting the heat from low-grade energy sources for cooling purposes.
24 gru 2020 · The manuscript focuses on reviewing studies in absorption refrigeration systems that use ammonia and absorbents, such as water, lithium nitrate, and lithium nitrate plus water.
1 lip 2019 · One year later, Costiuc and Costiuc (2010) carried out a theoretical study of a solar-powered ammonia/water absorption–resorption refrigeration system. They analyzed the performance of the cycle at different heat source temperatures provided by the solar collector.
